What determines what type of anchor to use?

The type of anchor to use is determined by several factors, including the weight and type of the object being anchored, the material of the surface (e.g., drywall, concrete, wood), and the environmental conditions (e.g., indoor vs. outdoor use). Additionally, the anchor's load capacity and the required permanence of the installation play a crucial role in the selection process. It's essential to match the anchor type to the specific application to ensure safety and stability.
